Chief Belmar said that there had been two more shootings in the area, and that the police had used smoke canisters.

The injured man, who was not publicly identified, was part of one of the rival groups, the chief said, and four plainclothes officers saw him running across a parking lot on the opposite side of the avenue.

The officers drove their unmarked sport utility vehicle, with its interior lights flashing, toward him, and he opened fire on the car, Chief Belmar said. The police returned fire from inside the car and then chased the man on foot, he said. Dozens of gunshots were fired, and all four officers shot back and hit the man, who fell to the ground, he said….
